The term fuzzy logic is used in this paper to describe an imprecise logical system, FL, in which the truth-values are fuzzy subsets of the unit interval with linguistic labels such as true, false, not true, very true, quite true, not very true and not very false, etc. The truth-value set, , of FL is assumed to be generated by a context-free grammar, with a semantic rule providing a means of computing the meaning of each linguistic truth-value in as a (...) fuzzy subset of [0, 1].Since is not closed under the operations of negation, conjunction, disjunction and implication, the result of an operation on truth-values in requires, in general, a linguistic approximation by a truth-value in . As a consequence, the truth tables and the rules of inference in fuzzy logic are (i) inexact and (ii) dependent on the meaning associated with the primary truth-value true as well as the modifiers very, quite, more or less, etc. (shrink)

A total of 944 expressed sequence tags generated 2212 EST loci mapped to homoeologous group 1 chromosomes in hexaploid wheat. EST deletion maps and the consensus map of group 1 chromosomes were constructed to show EST distribution. EST loci were unevenly distributed among chromosomes 1A, 1B, and ID with 660, 826, and 726, respectively. The number of EST loci was greater on the long arms than on the short arms for all three chromosomes. The distribution of ESTs along chromosome arms (...) was nonrandom with EST clusters occurring in the distal regions of short arms and middle regions of long arms. Duplications of group 1 ESTs in other homoeologous groups occurred at a rate of 35.5%. Seventy-five percent of wheat chromosome 1 ESTs had significant matches with rice sequences, where large regions of conservation occurred between wheat consensus chromosome 1 and rice chromosome 5 and between the proximal portion of the long arm of wheat consensus chromosome 1 and rice chromosome 10. Only 9.5% of group 1 ESTs showed significant matches to Arabidopsis genome sequences. The results presented are useful for gene mapping and evolutionary and comparative genomics of grasses. (shrink)

This book is about the ethical issues that clinicians encounter as they care for patients and is written to assist those who serve on hospital ethics committees as they deliberate about appropriate action in difficult ethical cases.

This paper challenges the traditional assumption that descriptive and prescriptive sciences are essentially distinct by presenting a study on the implicit normativity of the production and presentation of biomedical scientific facts within evidence-based medicine. This interdisciplinary study serves as an illustration of the potential worth of the concept of implicit normativity for bioethics in general and for integrated empirical ethics research in particular. It demonstrates how both the production and presentation of scientific information in an evidence-based decision-support contain implicit presuppositions (...) and values, which pre-structure the moral environment of the clinical process of decision-making. As a consequence, the evidence-based decision support did not only support the clinical decision-making process; it also transformed it in a morally significant way. This phenomenon undermines the assumption within much of the literature on patient autonomy that information disclosure is a conditional requirement before patient autonomy even starts; patient autonomy is already influenced during the production and presentation of information. These results imply an increased responsibility of those who produce and present evidence-based facts(i.e. scientists in general and physicians in particular). The insights of this study not only involve a different focus on both theory and practice of patient autonomy and informed consent, but they also call for a broader scope of morality than does traditional empirical research in bioethics. The concept of implicit normativity within integrated empirical ethics research calls for a strong cooperation between bioethicists and descriptive scientists, i.e., a cooperation that goes beyond the discipline-specific epistemic values and that takes place during all phases of the research process.

Bioethics represents a dramatic revision of the centuries-old professional ethics that governed the behavior of physicians and their relationships with patients. This venerable ethics code was challenged in the years after World War II by the remarkable advances in the biomedical sciences and medicine that raised questions about the definition of death, the use of life-support systems, organ transplantation, and reproductive interventions. In response, philosophers and theologians, lawyers and social scientists joined together with physicians and scientists to rethink and revise (...) the old standards. Governments established commissions to recommend policies. Courts heard arguments and legislatures passed laws. This book is the first broad history of the growing field of bioethics. Covering the period 1947-1987, it examines the origin and evolution of the debates over human experimentation, genetic engineering, organ transplantation, termination of life-sustaining treatment, and new reproductive technologies. It assesses the contributions of philosophy, theology, law and the social sciences to the expanding discourse of bioethics. Written by one of the field's founders, The Birth of Bioethics is based on extensive archival research into sources that are difficult to obtain and on interviews with many of the leading figures in the moral debates in medicine. A very readable and comprehensive account of the evolution of bioethics, this book stresses the history of ideas but does not neglect the social and cultural context and the people involved. It will serve the information needs of philosophers, ethicists, social historians, and everyone interested in the origins of some of today's most hotly debated issues. (shrink)

The Origin of Human Nature offers an original and fertile way to integrate spiritual and scientific views of human evolution. It offers a new and refreshing alternative to the way we think about our origins - random mutation (mechanistic neo-Darwinism), Genesis (God did it all personally), and Intelligent Design (God personally does what we can't otherwise account for). The result is an invigorating perspective on how our best qualities - our capacity for love, our appreciation of beauty, our altruistic capability, (...) our creativity and our intelligence - have come into being and evolved. By showing evolution as a creative and intelligent process with its own inherent logic, The Origin of Human Nature resolves the dilemma of how to have both truth and ethics at the same time. Instead of starting in an imagined remote and uncertain past and moving to the present, this book starts at the certain and immediate present and works back. That consciousness, creativity, and intelligence exist is certain. The question is, how can these have evolved? Dr. Albert Low has made a study of human nature throughout his life. In writing this book, he draws on his prolonged meditations on creativity and the human condition, his years of providing psychological and spiritual counseling, and a wide-ranging knowledge of Western psychology, philosophy, and science. He takes issue with Richard Dawkins' published texts, and provides a point-by-point rebuttal of the neo-Darwinist argument. (shrink)

When humans are required to perform two or more tasks concurrently, their performance declines as the tasks get closer together in time. Here, we investigated the mechanisms of this cognitive performance decline using a dual-task paradigm in a simulated driving environment, and using drift-diffusion modeling, examined if the two tasks are processed in a serial or a parallel manner. Participants performed a lane change task, along with an image discrimination task. We systematically varied the time difference between the onset of (...) the two tasks and measured its effect on the amount of dual-task interference. Results showed that the reaction times of the two tasks in the dual-task condition were higher than those in the single-task condition. SOA influenced the RTs of both tasks when they were presented second and the RTs of the image discrimination task when it was presented first. Results of drift-diffusion modeling indicated that dual-task performance affects both the rate of evidence accumulation and the delays outside the evidence accumulation period. These results suggest that a hybrid model containing features of both parallel and serial processing best accounts for the results. Next, manipulating the predictability of the order of the two tasks, we showed that in unpredictable conditions, the order of the response to the two tasks changes, causing attenuation in the effect of SOA. Together, our findings suggest higher-level executive functions are involved in managing the resources and controlling the processing of the tasks during dual-task performance in naturalistic settings.

This article explores emotions and their relationship to ‘somatic responses’, i.e., one’s automatic responses to sensations of pain, cold, warmth, sudden intensity. To this end, it undertakes a Husserlian phenomenological analysis of the first-hand experience of eight basic emotions, briefly exploring their essential aspects: their holistic nature, their identifying dynamic transformation of the lived body, their two-layered intentionality, their involuntary initiation and voluntary espousal. The fact that the involuntary tensional shifts initiating emotions are irreplicatable voluntarily, is taken to show that (...) all emotions have an innate core, a conclusion corroborated by their strong similarities to somatic responses in dynamics, hedonic tone, and topology. The fact that emotions may be culturally reworked, is shown to be explicable in terms of their complex nature: their dependence on belief, their voluntary espousal, and their ready social transmittability. Finally, it is argued that emotions may plausibly be deemed the evolutionary descendants of somatic responses. (shrink)

Peer review poses many challenges for journals. A downside of high rejection rates and sometimes delayed responses in publication decision by journals is a long time period between original submission of a manuscript and its ultimate acceptance and publication. One way of accelerating the process which might be worth considering is multiple submission. This commentary addresses that issue.

As Descartes noted, a proper account of the nature of the being one is begins with a basic self present in first-person experience, a self that one cannot cogently doubt being. This paper seeks to uncover such a self, first within consciousness and thinking, then within the lived or first-person felt body. After noting the lack of grounding of Merleau-Ponty’s commonly referenced reflections, it undertakes a phenomenological investigation of the body that finds the basic self to reside in one’s espoused (...) feelings and striving, both bodily in nature. It then examines the relationship of the lived body to the visual body and to the body studied by science. Two issues concerning that relationship are taken up. It is concluded that on the available evidence neither the apparent agency nor the apparent free will of the lived body is illusory. (shrink)

Albert Lautman (1908-1944) was a French philosopher of mathematics whose work played a crucial role in the history of contemporary French philosophy. His ideas have had an enormous influence on key contemporary thinkers including Gilles Deleuze and Alain Badiou, for whom he is a major touchstone in the development of their own engagements with mathematics. Mathematics, Ideas and the Physical Real presents the first English translation of Lautman's published works between 1933 and his death in 1944. Rather than being (...) preoccupied with the relation of mathematics to logic or with the problems of foundation, which have dominated philosophical reflection on mathematics, Lautman undertakes to develop an understanding of the broader structure of mathematics and its evolution. The two powerful ideas that are constants throughout his work, and which have dominated subsequent developments in mathematics, are the concept of mathematical structure and the idea of the essential unity underlying the apparent multiplicity of mathematical disciplines. This collection of his major writings offers readers a much-needed insight into his influence on the development of mathematics and philosophy. (shrink)

A many-worlds interpretation is of quantum mechanics tells us that the linear equations of motion are the true and complete laws for the time-evolution of every physical system and that the usual quantum-mechanical states provide complete descriptions of all possible physical situations. Such an interpretation, however, denies the standard way of understanding quantum-mechanical states. When the pointer on a measuring device is in a superposition of pointing many different directions, for example, we are to understand this as many pointers, each (...) in a differentworld, each pointing in a different determinate direction. We ask here whether such talk makes any genuinely intelligible sense of the term world. We conclude that it does not. (shrink)

This article examines the various Liar paradoxes and their near kin, Grelling’s paradox and Gödel’s Incompleteness Theorem with its self-referential Gödel sentence. It finds the family of paradoxes to be generated by circular definition–whether of statements, predicates, or sentences–a manoeuvre that generates pseudo-statements afflicted with the Liar syndrome: semantic vacuity, semantic incoherence, and predicative catalepsy. Such statements, e.g., the self-referential Liar statement, are meaningless, and hence fail to say anything, a point that invalidates the reasoning on which the various paradoxes (...) rest. The seeming plausibility of the paradoxes is due to the fact that often the sentence used to make the pseudo-statement is ambiguous in that it may also be used to make a genuine statement about the pseudo-statement. Hence, if a formal system is to avoid ambiguity and consequent paradox and contradiction, it must distinguish between the two statements the sentence may be used to make. Gödel’s Theorem presents a further complication in that the self-reference involved is sentential rather than statemental. Nevertheless, on the intended interpretation of the system as a formalization of arithmetic, the self-referential Gödel sentence can only be an ambiguous statement, one that is both a pseudo-statement and its genuine double. Consequently, the conclusions commonly drawn from Gödel’s theorem must be deemed unwarranted. Arithmetic might well be formalized in a proper system that either excludes circular definition or introduces disambiguators. (shrink)

The various roles proposed for emotion, whether psychological such as preparing for action or serving prior concerns, or biological such as protecting and promoting well-being, are easily shown to have an awkward number of exceptions. This paper attempts to explain why. To this end it undertakes a Husserlian phenomenological examination of first-person experience of two types of responses, the various somatic responses elicited by sensations (pain, cold, pleasure, sudden intensity) and the various personal directed emotions (grief, fear, affection, joy). The (...) analysis brings out the overall close structural symmetry between the two types of response and the strong hedonic, dynamic, and topological similarity between particular members from each of the two groups. The findings strongly suggest that emotions evolved from the more rudimentary involuntary somatic responses. The hypothesis finds further support in the fact that it explains both the biological unsoundness and anomalous archaic features that emotions often display. It also explains why emotions have no tidy function. (shrink)
